To all whom it may concern.:

'Be it known that l', Tnoirns W VARm, a citizen of the United States o America' residing at New York, in the unty o N ew York and State of New York, have invented new and useful Improvements in Electrical Systems7 rof which the followin is a full, clear, and exact description, re erence being had to the accompanyin drawing, which forms part of this specication. 'in' Letters Patent 1,081,413., 'anted Dember'lth, 1913, to Richard yarley, there is disclosed an electrical system employing transformer means whereby a high tension and effectively snstained flow of current isk aifordcd at a current using instrumentality,

such asua spark plug forming part-of the 'ignitior e uipment of internal comhustion engines he transformer specifically illustrated therein employs a choke coil or winding for controlling inductive reiationship betwec an energizing winding and a sccf winding; suitable make and 'creek mechanism being included in the circuit of the choir@- 'coil to effect intermittent charges of energy at the instrument.

.An improvement of that system, constituting my linvention is an arrangement wherein the said choke coil may be em loyed as an active energizing winding after iieing l'n'ought out of short circuit, to assist the main energizing winding in building up a larve bof, y of tiux in such manner as to elfes tained induction of a current in the secondary winding, `as will more fully appear from the following description of my invention made in connection withV the acig diagrammatic drawing, so that others slriilcd in the art to which it apper tains' may understandv and. construct the same. Y A

The numeralV 2 indicates a magnetizable member or core the leg 3 of which carries a winding 4. An opposite leg of the core carries a winding 6 in the circuit of `which is interrupter mechanism 7 comprising a iixed contact 8, a movable' contact 9 and an actu ating cam 10. The interrupter 7 normally short circuits the winding 6 through closure of the contacts Sand 9. Closure of these contacts alsov connects the' winding 4, through ground 1l, in the active circuit of a source 12 of current comprising 'preferably an alternating current generator one end of the generative windingof which is Specification of Innenraum.

ounded, as at 13. A hand switch 14 may included in the circuit of the winding` 4.

As clearly described in the above recited Letters Patent to Richard Varley, when the winding 4 is energized from tlie'source of alternating current, .a magnetic flux is set up' in the transformer core W'itli the winding 6 normally 'short circuited, the lines of 'force are repressed from the legr 5, so that the flux tends to take a leakage path across the side of the transformer. terrupter mechanism 7 is actuated in synchronism with the alternating current phases and is of such character that when the alternating current wave approaches or reaches the maximum peak or Iperiod of How, the cam 10 will kick'the contact 9.away from contact 8 andopen the circuit of the coil or winding 5 through the contacts 8 and As a result, the' repressed fiux is restored to normal in seeking the magnetic path provided' bythe leg 5. This inrush of iux at a high rate of change instantaneously builds up or induces a high potential current in a secondary windin 6a also dis posed on the leg 5 and one en of which is grounded as at 15; the-Opposite or live end The inleading to a suitable spark yplug distributor apparatus or any suitable current using instrumentality, as will be wellvunderstood by those skilled inthe art. However, upon opening of the short circuit of the winding- 6, the winding Gis also brought intov circuit with lthe generator through the ground 1l, so that this winding now becomes an active winding, and a resultant linx is induced in. the'leg 5, whichaugmentsand follows' the flux set up by the winding 4, discharged through the leg 5 upon opening of the short circuit of the Winding 6. The flux action in the trans-former core, and particularly through the leg which carries the secondary winding 6, is thus sustained to s'uch an extent-that there is a prolonged energizing of the current using instrumentality or spark plug connected in the circuit 'of the secondary. 1

Inasmuch as the winding 6 is not connected in the generator circuit until the sorb any sparking that may result under peculiar conditions.

/Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A magnetizable member', a source of energy, a plurality or" windings for inductively energizing the member, make andA Vrelated to said member, and having in circuit a current using instrumentality.

3. In an electrical system, a source ofV energy, a Winding, a second winding, and a third Winding connected in circuitwit-h the rst Winding, and means for bringing the irst and third windings into and out of series with each other and with the source' of energy, including make and break mechanism for the circuit of said first and third Wiudinffs.

In an electrical system, a primary winding, a secondary Winding, a source 'of energy, and means for bringing the secondary Winding into andout of inductiverelat-ionsliip with the primary winding, comprising a choke coil and means for connect,- ing said choke coil in series with the primary Winding and with the source of energy.

5;`n an electrical system, energy, a primary Winding, a secondary winding, means Jfor bringing the secondary winding into and out of inductive relationship with the primary winding, comprising a source of a choke coil and means for connecting said choke coi'l in series with the primary winding and source of energy.

6. In an electrical system, a transformer core, and means for creating a nur; therein and for causing said flux to be repressed, comprising a source of energy, a plurality of windings connected in series with said source and ineens for short circui-ing one of said windings.

'7. In an electrical system,y a transformer core, means for creating a finir tliercin'and for causing said flux to be repressed from the core, comprising a source ot energy, a plurality. of windings connected in series with said source and means for short circuiting one of said windings, and a coil inductively related to said core.

8. In an electrical system, a transformer core, means for creating a linx therein, 'for causing said flux first to be repressed from said core and then to traverse it. comprising a source of energy and a plurality Windings connected in series `with said source and means for short ci'rcuiting one o'f said windings, and a coil inductively relati 'l to said core.

9. In an electrical system, a "plurality of windings, and means for energizing one of said windings, for transferring f id energy and supplying energy to a second one of said windings, comprising a source oi current and a third one of said windings connected in series therewith and .e ns for short circniting said third Winding.

l0. A source of energy, a transf-sinner core, two windings connected in series with said source for creating a flux in said core, means for intermittently Short circniting one o1 said vwindings, so as to alternately oppose and cause passage of flux tlironffh the core, and another 4winding inductii'eiy related to said irstwindings.

In 'testimony whereof, I have hereunto set l my hand.
